Vertical Fire Tube Heat Exchanger
What makes the vertical Fire Tube heat exchanger so unique? Constructed of robust chromium stainless steel with a down-fired design, this heat exchanger resists combustion chamber damage, scale build-up, and magnetite formation better than other heat exchanger types on the market - prolonging its lifetime and reducing maintenance. The dimpled fire tubes extract more heat while remaining compact, without the need for inserts that degrade over time.
Absolute Efficiency
The stainless steel Elite Fire Tube Ultra offers high efficiency, low pressure drop, and performance you can depend on. These models include an outdoor sensor that when used provides an AFUE rating of up to 96%, ensuring savings on your monthly energy bills. The 10:1 turndown ratio limits short cycling for more efficient energy consumption. The Elite Fire Tube Ultra also comes equipped with a built-in highly efficient ECM Pump.
